please try to eliminate the problem by using one

of the following measures:

Relocate either this product or the device that is

being affected by the interference.

Use power outlets that are on different branch

CAUTION:

READ THIS BEFORE OPERATING YOUR UNIT

1. To ensure the nest performance, please read

this manual carefully. Keep it in a safe place for

future reference.

2. Install your unit in a cool, dry, clean place -

away from windows, heat sources, and too much

vibration, dust, moisture or cold. Avoid sources of

hum (transformers, electric motors). To prevent

re or electrical shock, do not expose to rain

and water.

3. Do not operate the unit upside-down.

4. Never open the cabinet. If a foreign object

drops into the set, contact your dealer.

5. Place the unit in a location with adequate

air circulation. Do not interfere with proper

ventilation; this will cause the internal

temperature to rise and may result in a failure.

6. Do not use force on switches, knobs or cords.

When moving the unit, rst turn the unit off. Then

gently disconnect the power plug and the cords

connecting to other equipment. Never pull the

cord itself.

7. Do not attempt to clean the unit with chemical

IEM-900R/T | 11

solvents: this might damage the nish. Use a

clean, dry cloth.

8. Be sure to read the “Troubleshooting” section

on common operating errors before concluding

that your unit is faulty.

9. This unit consumes a fair amount of power

even when the power switch is turned off. We

recommend that you unplug the power cord from

the wall outlet if the unit is not going to be used

for a long time. This will save electricity and help

prevent re hazards. To disconnect the cord, pull

it out by grasping the plug. Never pull the cord.

10. To prevent lightning damage, pull out the

power cord and remove the antenna cable during

an electrical storm.

11. The general digital signals may interfere with

other equipment such as tuners or receivers.

Move the system farther away from such

equipment if interference is observed.

Be sure to position the voltage selector to match

the voltage of your

local power lines before

installing the unit.
